Mystery Master rebuild/power drum
 

Hello dear friends,

I am looking for any info on when, where, and by who this master cylinder was rebuilt. One opinion is that it was most likely Wheeler Industries, as they did Chrysler parts in USA. Rebuilds from china I have never seen, only a noticeable recast of some cylinders which are later ones (A1-Cardone crap). This one has been stored in a climate controlled building and is an original as designated by the casting, with the original side bolt piston retainer as a production line unit. There is the yellow dot on the lid, and the yellow stamp "REMFG SC-M7" on the cylinder body. I have seen this yellow stamp type on other remans, even ones from places like A1-Cardone, and wonder; is this a standard marking in the rebuild industry? Original casting on body is 2225601. Hope this info helps. Some pics attached.

Thank all!

-- Why do you want to know this ? --- Just curious. ---------- https://moparforums.com/forums/images/icons/icon7.gif

Hey Magoo,

Because the quality of the rebuild directly and significantly affects my ability to stop a 3700 lb Plymouth. Because it's important. Also because I want the inner replacement components to have the OM flow capacity and performance that a proper rebuild with proper parts provides. Rebuild.. not De-build.

Anyone else..

Thanks ;-)

I would shoot a guess on it being an ICE MFG unit.....
If your going to rebuild it yourself.... Get the Wagner kit to install in the unit..

Just my 2 cents

Thanks Bob,

The original one on my 67 Plymouth was replaced by 1st owners mechanic with a cheap Chinese re-cast that provides no assist at all. So unfortunately I don't have the original unit to rebuild.

This one in the photos is being sold as an original cast rebuilt unit, which would be correct for my car. Do you know if ICE MFG Is a high quality rebuilder?

Thanks, Alex

Answer
 

Magoo,

Not sure why you asked the question as an answer to my question in the first place, but I answered your question with an honest answer.. not another question. One thing I never question is my integrity, so why would I think that you would.

However, the integrity of this master cylinder rebuild is definitely in question.. As my, um, question clearly questions ;-)

I would question the Cups and seals if that is a true OEM Cast Iron Master. Seals are more than likely old and dry. But if it is not pitted and rusted. It would make for a good rebuild-able core i would say.

ICE MFG. was a great MFG.... But they have been out of business for quit some time now... But yes.... One of the highest quality... I always had great luck with them..Looks close to the one on my old 1967 Dodge Monico I use to own. :)

I ended up stripping the old stock cylinder of its Pistons, brass seats, springs, lid gasket, etc, and I sent it to Brake Equipment Warehouse in Mineappolis. They first media blasted and powder coated it the original grey. Then their master machinist Brad over bore and pressed in a 1" stainless steel sleeve, and drilled out the ports. Beautiful machine work. In the meantime I found an NOS Chrysler rebuild kit on eBay, complete with springs, brass seats, pistons, and lid gasket. I polished the lid out and had it replated factory color... and also had the pb booster rebuilt and plated by Booster Dewey! I highly recommend those guys to all. Nice work fellas!
